Whitelisting has been a buzzword used in the industry for the past 18 months or so, and is seen by some as a Panacea to beat Malware spreading within organisations and control threats inside your environment. Indeed, some of Symantec’s products use Whitelisting as an additional method of controlling software behaviour and limiting the applications that employees can or cannot use.
Whitelisting generally involves a process of learning exactly which applications, operating system components and hardware drivers are installed on a server or workstation, collating that information centrally, and then allowing an administrator to approve or deny the use of these tools.
Once this process has initially completed, enforcement of this list of applications is then applied to the target machines. Theoretically, this has given control back to the organisation in relation to what software is allowed to run on the corporate computers.
